You cannot exit something that no longer exists.
I'm in Paris this weekend covering the first round of French presidential elections, a historic contest which will have a profound impact on Europe and the world.
Tomorrow's first round of voting could result in a run-off between a far-left and a far-right candidate, both of whom are hostile to the European Union and have in the past called for France to leave the EU. The latest polls show a race that is anyone's game, and could result in any number of second round combinations across the political spectrum. It is an election like France has never seen, and nobody knows that tomorrow will bring.
A first round win for far-right nationalist Marine Le Pen and far-left communist Jean-Luc Mélenchon would send shock waves throughout the world. It would not only mean the collapse of the mainstream political infrastructure in France. It would put the future of Europe, and of Western liberal democracy as a whole, in terrifying doubt.
